Glasses that can see through cards are a necessity for some poker players. In addition to being stylish, they also help detect marked cards in games.
These glasses can be made of several different materials and come in many colors. They are easy to wear and have a soft, light feel that is comfortable on the face. They are also very durable and can withstand daily wear and tear.
They are perfect for reading marked cards that you have bought at a poker shop or have gotten from someone online. They are also great for watching television or movies, as they can prevent you from getting too bright or causing your eyes to hurt.
Anti-reflective lenses reduce glare from light sources, making it easier to read. They can be tinted and have different colors, so they’re a good choice for anyone who spends a lot of time in the sun or outdoors.
They are also great for preventing glare on electronic devices like laptops and tablets, as they have a special filter that blocks harmful blue light. They do have a downside, however: they may cause the screens to look more orange or red.
Plastic photochromic lenses have carbon-based compounds within them that change their structure in the presence of UV rays, turning them into darker lenses as they absorb more sunlight. They’re a bit cheaper than glass photochromic lenses, but they’re still a smart investment.
These lenses aren’t as effective at blocking blue light as a pair of sunglasses. But they’re a good option for people who aren’t able to buy glasses with prescription lenses.
Infrared sunglasses are another popular option among poker players, who use them to detect other poker players who have marked their cards. This type of sunglasses is called luminous ink glasses because they have red filters built into their lens, which are used to detect the invisible luminous ink marks on the backsides of marked cards.
They’re also a good choice for people who have a tendency to sweat, because they’re less likely to slip down the face than glasses that are all acetate. This is especially true if you have a frame that has nose pads, which can make them more stable on your face.
You’ll find these measurements on the arms of most glasses, in a series of numbers that follow the same order and have standard ranges, all expressed in millimeters. They’re an important part of the eyeglass buying process, as they determine your glasses size and help you find a fit that works best for you.
There are a few other measurements that you’ll probably encounter on the inside of your glasses, although these usually aren’t displayed on the frame itself. These can be helpful in determining how well your glasses fit and perform, but they’re not always the most accurate measurements.
The lens width, which is the widest part of the glasses, is the first measurement in the series. This is the measurement of the clear part of your glasses that you look through, and it’s the largest of the measurements you’ll want to know.
